Ok, bought myself the Wii fit plus in the hope that that could count towards doing some exercise.
I do try at most times to stay in so the gym is totally out of the question.

Do you think that this can help even if its just a little?

Lilyfrog,
Every type of physical activity helps. There is nothing magical about a gym. What makes the difference is a desire to exercise in any form. Yeah exercise is demoralizing and hard when you first start because it makes you realize how long and hard the path will be. But once your on it you won't want to get off of it. Keep at it, you WILL BE SUCCESSFUL!
